So this comes with a large paper that you tape up straight on the wall that shows you exactly where to screw the holes. I have tried putting up photo arrangements and now I usually don’t bother because it’s a nightmare getting the alignment and spacing right for me. This takes all of that work away and does it for you, so you can get a professional looking arrangement for no effort. I ordered the photos online to get printed in various shades of black and white and sepia, which I think goes well with the mix matched frames. I picked some of my immediate family and some ancestors.
